Hi,

sry, for my late reply.
Thank you for your answer.

I'm not able to build hyperion ng in CoreELEC, because there is no package manager...
I took a second SD card, installed Ubuntu 20.04 (https://wiki.odroid.com/odroid-c2/os_images/ubuntu/v4.0)
and compiled hyperion ng as described here: https://github.com/hyperion-pr…ob/master/CompileHowto.md

With this build i got not this error and the LEDs are lightning.

I have no idea how to ring-fence the problem now...

Maybe @Portisch can help?

Thanks

Hello,

i want to build my own ambient light with an Odriod C2 + LED SK9822 (like APA102) on SPI with CoreELEC and Hyperion NG.

CoreELEC: 9.2.3
Hyperion NG: bulid on 14.07.2020 (https://discourse.coreelec.org/t/hyperion-ng-amlogic-improvements/5476/172)

I connected 150 LEDs with the Odroid C2:

• LED DI -> MOSI (PIN 19)
  

  
  

• LED CI -> SCLK (PIN 23)
• GND -> GND (PIN 25)
  

  
  

• Powersupply 5V / 20A

and got this error:

[hyperiond LEDDEVICE] (ERROR) SPI failed to write. errno: 14, Bad address

The SPI device works. I tested it with "spidev_test" program:

What does this error mean?

Thanks
